If the installer[1] is booted from an optical drive, the "No disk drive was detected" error is shown.[2] However, if the installer is booted from a USB stick,[3] the installer disk is shown as the only choice in partman. If it is selected, either the "[...] the selected disk or free space is too small [...]" (if the USB stick is ~2GiB or less) or the "unable to inform the kernel of the change" error after overwriting the installation media, as in the preseed use case.
